| As soon as the three Orchidean forms, Monachanthus,
Myanthus, and Catasetum, which had previously been ranked as three distinct genera, were known to be sometimes produced on the same plant, they were immediately considered as varieties; and
now I have been able to show that they are
the male, female, and hermaphrodite forms of the same species.

on the subject, these tumblers are kept in the same group, because allied in blood and alike in some other respects. If it could be proved that the Hottentot had descended from the Negro, I think he would be classed under the Negro group, however much he might differ in colour and other important characters from negroes. |

| With species in a state of nature, every naturalist has in fact brought descent into his classification; for he includes in his lowest grade,
that of
species, the two sexes; and how enormously these sometimes differ in the most important characters, is known to every naturalist: scarcely a single fact can be predicated in common of the
and hermaphrodites of certain cirripedes,
and yet no one dreams of separating them. ↑
The naturalist includes as one species the
larval stages of the same individual, however much they may differ from each other and from the

the so-called alternate generations of Steenstrup, which can only in a technical sense be considered as the same individual. He includes
varieties, not

the parent-form, but because they are descended from it. He who believes that the cowslip is descended from the primrose, or conversely, ranks them together as a single species, and gives a single definition. As soon as three Orchidean forms (Monochanthus, Myanthus, and Catasetum), which had
been ranked as three distinct genera, were known to be sometimes produced on the same spike, they were immediately included as a single species.
